Title

Effect of thermal processing in steam environment on texture, juiciness, and collagen solubility in beef top blade muscle

Abstract

A beef top blade muscle (m. infraspinatus) was evaluated in order to determine the possibility of its culinary application; the muscle evaluated was from cattle, which was a cross-breed of the Polish dairy cattle and Limousin breed. The basic chemical composition (water content, protein, fat, collagen, mineral compounds assayed as ash) of the whole raw muscle meat were determined as were its colour parameters (L*a*b*). The parts of the muscle: head, middle part, and tail were cooked in a convection steam oven so as to obtain a temperature 75, 85, 95 ºC, respectively, inside the element. After the cooking completed, in every part cooked, the following parameters were determined: cooking loss in each part, content of muscle and soluble collagen, colour parameters, and shear force. The sensory evaluation was also conducted. It was proved that the muscle, weighing 2668 g on average, was characterized by the colour parameters typical for culinary beef from beef cattle. It contained 76.02 % of water, 20.13 % of proteins including 1.94 % of collagen, 2.79 % of fat, and 0.98 % of mineral compounds. Cooking the muscle in the convection steam oven to the temperature ranging from 85 to 95 ºC inside the cooked part significantly decreased the toughness, advantageously impacted the degree of collagen protein solubility, and beneficially influenced sensory parameters of the cooked meat, such as tenderness, taste and overall acceptability.
